A Complete Guide to Reese Witherspoon's Hello Sunshine Book Club Picks

"The Guest List" by Lucy Foley ($15)

• What it's about: Taking place on a rainy, remote island outside Ireland, this book begins with a picture-perfect wedding. But as the alcohol begins to flow, old conflicts start to emerge, and suddenly someone winds up dead, leaving the rest of the party to search for the killer in their midst.
• What Witherspoon says: "This book is a true thriller . . . It has all kinds of twists and turns and it reminded me of some of my favorite stories from Agatha Christie."
